OK, so I haven't blogged in over a week, time to get back on the horse. OBE is progressing well, but I have been trying to divide my time amongst several things (familt, other projects, work around the house, etc.) I have to finish the XPDL serializer implementation and tweek the engine a bit but then I will release the first alpha version. I still have a lot of work on data types as well as facilities for monitoring the engine at runtime. The devil's in the details.
